Gmail Inbox Triage
==================
A personal inbox triage agent that learns your preferences across sessions.

Combines Gmail tools with the Learning Machine to build persistent memory:
- Learns your communication tone and style
- Remembers frequent contacts and relationships
- Adapts drafts to match your writing patterns
- Uses date awareness for time-relative queries ("last week", "this month")

Key concepts:
- LearningMachine with UserMemoryConfig: Persistent preference storage
- add_datetime_to_context: Date-aware email queries without unix timestamps
- get_thread + get_message: Full context before drafting
- Multi-session learning: Agent improves with each interaction

Setup:
1. Create OAuth credentials at https://console.cloud.google.com (enable Gmail API)
2. Export GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_PROJECT_ID env vars
3. pip install google-api-python-client google-auth-httplib2 google-auth-oauthlib
4. Start PostgreSQL: cookbook/scripts/run_pgvector.sh
5. First run opens browser for OAuth consent, saves token.json for reuse

Use a stable, distinct user_id for each person whose preferences you store; the displayed address is a placeholder. The first run can extract preferences through LearningMode.ALWAYS, while the second session is commented out. Keep the same database and user ID when enabling it. Learning is model-driven and does not guarantee a new memory on every run. The toolkit's Google account is chosen by OAuth credentials, independently of these learning IDs.

Run the Example

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Install dependencies

uv pip install -U agno "psycopg[binary]" google-api-python-client google-auth google-auth-httplib2 google-auth-oauthlib openai sqlalchemy

Configure Google OAuth

Enable the Google API used by this example, configure the consent screen, and create a Desktop OAuth client in your Cloud project. Export its GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, and GOOGLE_PROJECT_ID, or place the downloaded client JSON at credentials.json in the directory where you run Python. Google's Python quickstart shows the Desktop client setup.

The first tool call opens a browser for consent and caches credentials in token.json. Use a separate token_path when switching accounts. Passing an Agno user_id does not switch the authenticated Google account.

Export environment variables

export GOOGLE_CLIENT_ID="your_google_client_id_here"
export GOOGLE_CLIENT_SECRET="your_google_client_secret_here"
export GOOGLE_PROJECT_ID="your_google_project_id_here"
export OPENAI_API_KEY="your_openai_api_key_here"

Run PgVector

docker run -d \
  -e POSTGRES_DB=ai \
  -e POSTGRES_USER=ai \
  -e POSTGRES_PASSWORD=ai \
  -e PGDATA=/var/lib/postgresql \
  -v pgvolume:/var/lib/postgresql \
  -p 5532:5432 \
  --name pgvector \
  agnohq/pgvector:18

Run the example

Save the code above as inbox_triage.py, then run:

python inbox_triage.py
